What Is "Plant Food" Poisoning?
"Plant food," also known as plant fertilizer, is commonly used on
plants in homes or gardens. Such fertilizers keep plants healthy and allow them
to grow faster.
Plant foods can be hazardous to people and pets through physical
contact, inhalation, or accidental ingestion. It is safe to use fertilizers on
nonedible plants, but you should always be cautious when handling and storing
plant food. If you want to fertilize edible plants, you should ask a
professional for advice about which products to buy.
According to the American Association of Poison Control Centers,
there were around 1,500 reported cases of poisoning from indoor household plant
foods in 2014. Including the instances caused by outdoor and unknown
fertilizers raises the number to nearly 5,000 cases in 2014. The majority of
cases were accidental poisonings in children under 5 years of age.
Symptoms of Plant Food
You may develop the following symptoms if you come into physical
contact with plant fertilizers:
- skin redness
- burning sensation on the skin
- itchy skin
- burning of the nose, eyes, or throat
You may experience these symptoms if you ingest plant
- body parts (such as your fingernails, lips, or
hands) turn blue from lack of oxygen
- low blood pressure
- shortness of breath
- upset stomach or stomach pain
What Causes Plant Food
Plant fertilizers can poison people and pets if they are inhaled
or accidentally ingested. Touching the fertilizer may cause skin irritation,
and ingesting it may be poisonous. Nitrates are the ingredients that cause the
Nitrates are a form of nitrogen that plants can easily absorb.
Nitrogen is essential for plant growth, but it can be very dangerous when
present at high levels in humans. Within our bodies, nitrates lower the ability
of the red blood cells to carry and deliver oxygen.
What to Do If You Are
Poisoned by Plant Food
If you believe you have been poisoned by plant food, you should
call the National Poison Control Centers hotline immediately. The emergency
number is (800) 222-1222. You should also seek medical help. When the
paramedics arrive, be sure to tell them:
- which fertilizer you were exposed to
- whether it was inhaled, ingested, or touched
- how much of the material you came in contact
- when the contact occurred
Get fresh air immediately if the plant food was inhaled.
If the plant fertilizer is in your eyes or on your skin, flush thoroughly
with water for at least 15 minutes.
If you ingested the substance, do not induce vomiting unless the
poison control center tells you to. You should drink water or milk, unless the
poison control center advises against it. Don’t drink anything if you are
vomiting as this could lead to choking or drowning. The same guidelines apply
if you are providing care to a victim who is vomiting or unconscious.
The poison control center may advise you to go to the hospital.
Once there, the staff will assess the severity of your poisoning.
Your doctor may run tests to check for methemoglobinemia. In
this condition, the nitrate binds to the hemoglobin in your blood. Normally,
hemoglobin is the compound that allows the blood cells to carry oxygen
throughout your body. When you have methemoglobinemia, your blood cannot
adequately circulate oxygen, causing a bluish tint in the oxygen-starved areas.
Since methemoglobinema is more common in infants, it is sometimes called
If necessary, doctors at the hospital may give you medications,
breathing support, or liquids intravenously.
Outlook for Plant Food
Your ability to recover from plant food poisoning depends on the
- what type of fertilizer you came into contact
- how much fertilizer you inhaled, ingested, or
- how much time passed before you sought medical
The faster you seek help, the better your chances of recovery.
Remember to always call your doctor or the poison control center if you think
you or a loved one may be suffering from plant food poisoning. It can be fatal
if not treated promptly.
